RELAY.

Specification'of Letters Patent.

Patented Feb. 9, 1909.

Application filed June 1, 1906. Serial No. 319,754.

To all whom it may concern:

Be it known that I, FRED B. Conny, a citizen of the United States, residing at Schenectady, county of Schenectady, State of New York, have invented certain new and useful Improvements in Relays, of which the follzowing is a specification. I

My invention relates to electromagnetic, and particularly to magnets'for use in trackrelays; and its object is to provide a novel, simple and economical arran ment for securely su porting the terminal bindingposts for tie coils.

My invention consists in providin the two magnet spools of a relay with endanges of insulating material having portions extend ing beyond the magnet coils for supporting the terminal binding-posts, and adapted to sup ort a binding-post between the flanges of e two spools.

My invention further consists in shaping each end symmetrically, so that the two magnet-spools are interchangeable in position.

My invention will best be understood by reference to the accompanying drawings, in which Figure 1 shows a plan-view of a relay ar ranged in accordance with my invention; Fig. 2 shows a side-elevation of the same; an Fig. 3 shows a perspective view of one of the end-flanges.

The relay shown in the drawings, comprises two magnet-spools A A mounted sidey-side on an insulatin supporting base B, with their cores joined at the top of the spools by a ma etic yoke C. The moving arts of the re ay are inclosed between the ase-plate B and a second base-plate D; the intermediate member. E being referably formed of glass, so as to permit t e inspection of the moving parts.

F represents the armature pivoted at f, carrying a contact member G adapted to en ga e The current is led to orfrom the con tact member G by a flexible spiral'member I, which connects the contact member to the 0st J. The construction, thus far describe is similar to that ordinarily cmployedin devices of this character, and forms no part of my invention.

The up er end-flanges K of the ma net coils are owned of insulating materia, as usual, but are made somewhat heavier, and are extended beyond the coil so as to receive the front contacts H or back contactsbinding-posts L, to each of which one ter minal of one magnet-coil is connected. These binding-posts act as connections between'the relay terminals and the track or source of current. The end-flanges of the two in net-s ools are arranged to engage each oli ier a ong a line between the two spools, and are provided with opposite recesses la, in which the binding-post M is clamped between the two end-flanges. To this binding-post are connected the other terminals of both coils, so that the two coils are connected .in series through this bindingpost. It will be seen that each end-flange 1s provided with a second recess 1: symmet- 7 rically arranged with respect to the first recesses. These recesses 79' are not used with the two coils in the position shown, but render the two spools interchangeable in p0- tion, which is a material advantage in replacing damaged coils.

When a cylindrical casing is employed for inclosing the relav contacts, as shown in the drawings, with the magnet spools mounted eccentrically, it is desirable that the flanges at the upper ends of the magnet spools should not project beyond the periphery of the casing. The quadrilateral form of flange, which I have shown in the drawin with one diagonal lon er than the other, a fords a support for t e terminals at some distance from each other and from the magnet yoke, without projecting over the edge of the casing.

What I claim as new and desire to secure by Letters Patent of the United States, is,-

1. In a relay, two ma net spools mounted side by side having end-fie. s of insulating material, and -a termii binding-post clamped between said end- Ln 2. In a relay, two magnet s r-ols mounted side by side havin similar end-flanges of insulating materia engaging; each other along one side, each of said end flanges being of quadrilateral shape with unequal dingo Hale, and terminal binding posts mounted on said flanges near the ends of the longer diagonals.

3. In a relay, two ma net-spools mounted side-by-side having on flanges oi. insulating material engaging each other, and a terminal binding-post clamped between said end flanges.

4. In a relay, two magnet-spools mounted side-by-side having cnd-flanges of insulating llU * material on material en a ing each other, said flan es being provi e with op osite recesses, an a terminal binding- 0st c amped between said end flanges in sea recesses. 5. In a relay, two magnet-spools mounted side-by-side having end-flanges of insulating :(g'ing each other, said flanges provi 'with op osite recesses, and a terminal binding-post c amped between said arid-flanges in said recesses, each of said flanges having a second recess arranged symmetrically with respect to the first, whereby said magnet-spools are interchangeable in position.

6. In a relay, two ma et-spools mounted side-by-side having on -flanges of insulating material engaging each other, and a terminal binding-post clamped between said end-flanges, said flanges being symmetrically whereby the magnet-spools are inshagled,

terc angeable in position.

'7. In a relay, two ma et-spools mounted side-by-side having endangi'es of insulating material enga ing each ot er, a bindingpost clamped etween said end-flanges and connected to a terminal of both magnetcoils, and two binding-posts mounted on extensions of the flan es respectively and respectively connectef tothe other terminals of the two magnet-coils.

8. In a relay, two ma et-spools mounted side-by-side having endanges of insulating material engaging each other, a bindin -post clamped between said end-flanges an con nected to a terminal of both magnet-coils,

and two binding-posts mounted on extensions of the two flanges respectively and respectively connected to the other terminals of the two magnet-coils, said flanges being symmetrically shaped, whereby the magnetspools are interchangeable in position.

9. In a relay, two magnet-spools mounted side-by-side having end-flanges of insulating material engaging each other, said flanges being provided with opposite recesses, a binding-post clamped to a terminal of both magnet-coils, and two binding-posts mounted on extensions of the two flanges respectively and respectively connected to the other terminals of the two magnet coils, said flanges each having a second recess arranged symmetrically with res ect to the first, whereby the magnet-spools are interchangeable in position.

10. In a relay, a cylindrical casing, contacts inclosed therein, a pair of magnet spools for actuating said contacts mounted eccentrically on said casin and havin similar end flan es of insu atin materilfi engaging each ot er along one si e, each of said end flanges being of quadrilateral shape with unequal diagonals, and terminal binding posts mounted on said flanges near the ends of the lon er diagonals.

In witness w ereof, I have hereunto set my hand this 31st day of May, 1906.
